A partial clone of caldesmon, coding for the C-terminal 288 amino acids, was isolated from a human fetal liver cDNA library and sequenced. Expression of the clone in Escherichia coli produced a peptide called H1 (M r 32 549), which inhibited tropomyosin-enhanced actomyosin Mg2+-ATPase activity by 90
